MROVEMEN'I' m EXPLOSIVE GARTRIPQES.

dated December 29, 1838.

The Schedule referred to in these Letters Harem: and making pan. of the name.

To it may cmlwm:

Be it known that I, Senmrz, of the city and couutynflhiladelph @fltntl State of Pennsylvania,

nating-Oo'mbinationfor Making Explosive Cartridges ploded by percussion, concussion, or friction.

The nature of my invention consists in rolling paper the size of the gun. The other half of the roll is drilled out, and filled with the process or combination of heat will explode the combustible matter contained in these cartridges, that this combination is more efiective than gunpowder, and will drive a ball to .a much greater distance. I

my invention, I will proceed to describe its construction and combination.

I roll together, as tightly as possible, a number of layers of paper, of suflioient thickness, and in suitable lengths, for ,the gun for which they are to be used. In one end of these paper rolls, I drill a hole about half way through, into which I pour the following combination or process, composed ofamorphous phosphorus, one part, chlorate of potash, two parts, gum-arabic, three parts, water, one part, in the quantifies and proportions herein stated. In a few hours, thissubstance hardens, and assumes a solidified form. The'other end of this paper roll I hollow out, and

.fit. nto. it ahall-or shig, ada ted to the calibre or th gun-from which it is to be discharged.

I take strong linen paper, and saturate it'in a solution, composed, in equal parts, of brimstone, coal-oil, and gutta-pereha, of each' one part, which I roll around the entire cartridge, and fasten the edges or seam of this wrapper or cover with a glue made of vinegar, one part; white glue, one part; gum-ammoniac, one part; glycerine, one-eighth part; alcohol, one-half part.

. The covering of the cartridge with the linen paper, prepared and glued together as aforesaid, renders it completely water-proof.

The cartridge is made of paper, which, on account of its being rolled'tightly together, and the compression from drilling the holes, is harder than wood], while it is comparatively of but little weight, and is discharged by being struck by a ncedle in the gun, which, coming in contact with the combustible matter, discharges it.

This combination 'may be usedin the manufacture of percussion-caps, and other things'requiring a fuhnihating-combination.

What I claim as my invention, and desire to secure by Letters Patent, is- 1 A combination'of the articles above described, in and for the purposes setforth.
